# Catalog Preparation Guides

This directory contains the catalog preparation guides referenced from [Prepare Lakehouse Catalogs](../prepare-lakehouse-catalogs). Each guide focuses solely on the steps required to provision the catalog and the supporting cloud resources (storage buckets, IAM roles, service principals). Once a catalog is prepared, see [Configure Lakehouse Catalogs](../configure-lakehouse-catalogs) for how to wire it into the StreamNative Ursa compaction service.
